Shared library exists but claimed not found

["Aaron M. Stromas" <ams@izoard.com>]

Greetings,

On several occasions I had this problem when an application fails to 
start with "error while loading shared libraries: libxxxxxxx.so: cannot 
open shared object file: No such file or directory", yet the library is 
there and I have update the cache using ldconfig.

For example, I'm trying to get Skype running on AMD64:

sella:#/home/ams/# skype
skype: error while loading shared libraries: libqt-mt.so.3: cannot open 
shared object file: No such file or directory
sella:/home/ams/# ldd /usr/bin/skype
       linux-gate.so.1 =>  (0xffffe000)
       librt.so.1 => /lib32/librt.so.1 (0xf7f42000)
       libasound.so.2 => /usr/lib32/libasound.so.2 (0xf7e82000)
       libqt-mt.so.3 => not found
sella:/home/ams# locate libqt-mt.so.3
/usr/lib/libqt-mt.so.3
/usr/lib/libqt-mt.so.3.3
/usr/lib/libqt-mt.so.3.3.7
/usr/share/qt3/lib/libqt-mt.so.3
/usr/share/qt3/lib/libqt-mt.so.3.3
sella:/home/ams# ldconfig -v | grep libqt-mt.so.3
       libqt-mt.so.3 -> libqt-mt.so.3.3.7
sella:/home/ams/# ls -l /usr/lib/libqt-mt.so.3.3.7
-rw-r--r-- 1 root root 10390056 Oct 21 13:45 /usr/lib/libqt-mt.so.3.3.7
sella:/home/ams# /usr/bin/skype
/usr/bin/skype: error while loading shared libraries: libqt-mt.so.3: 
cannot open shared object file: No such file or directory

Any suggestions why the library isn't picked up? TIA.
